Yes, I understand that the power can work for water and fans during the day, should have clarified that the electricity won't go to waste completely. I know that Clearvue sell glass but IMO it wouldn't hurt for Clearvue to develop a storage solution to be able to deliver an all-in-one solution. Look at what Apple did when they identified an opportunity to make the iPhone. Good companies stagnate when they don't remain competitive, and there is already competition out there for Clearvue. 

I'll take a look, thanks.
